Free Pest Control Software in 2026: Invoicing, Scheduling, and Service History

Quick answer: Krib is one of the best free pest control software options in 2026 — recurring service plans for quarterly and bi-monthly treatments, per-stop invoicing with online card payment links, per-property service history with photos, and technician scheduling at $0/month with no per-user or per-route fees. Dedicated pest control platforms are all paid: GorillaDesk starts at $49/month per route (free trial, no free tier), while FieldRoutes, PestPac, and Briostack don't publish pricing at all — they're quote-only, demo-first enterprise products.

The Pest Control Billing Problem

Pest control has a workload shape most software ignores: a technician runs 10–20 stops a day, the majority are recurring quarterly or bi-monthly accounts, and every single stop needs to end with a service record and an invoice. Multiply that by a week and a two-tech operation is producing 100+ billable events — each one a small amount, each one easy to lose.

That's why searches in this trade skew so hard toward invoicing. A missed treatment gets noticed (ants come back; the customer calls). A missed invoice doesn't — the work happened, the chemicals got used, and the $85 just never arrived. At pest control volumes, even a small percentage of unbilled stops is real money by year end.

The industry's dedicated software solves this well — and prices accordingly. GorillaDesk starts at $49/month per route. FieldRoutes, PestPac, and Briostack are enterprise platforms that won't even show you a price without a sales call. For a solo operator or a two-truck company, this guide covers what the software actually needs to do, what the paid options cost where that's knowable, and how to get the core workflow — recurring plans, per-stop invoicing, online payments, service history — genuinely free.

(Krib also has a dedicated free pest control software page with the feature summary.)

What Pest Control Software Must Handle

Pest control is recurring-route work with a compliance layer on top. Before committing to any tool, check it against the six patterns the trade actually runs on:

1. Recurring treatment plans. Quarterly general pest, bi-monthly for heavier pressure, monthly commercial accounts — plans should regenerate visits automatically on their cadence, tied to the customer and property, without anyone re-entering them each cycle.

2. Route-day density. Profitability in this trade is stops-per-day. The schedule needs to group a day's work geographically so a tech runs a tight loop, not a county-wide scavenger hunt.

3. Per-property service history. "What did we treat, where, and when" — with photos and notes — needs to live on the property record permanently. It's what the tech reads before ringing the doorbell, what settles callbacks and disputes, and what makes the account transferable when a tech leaves.

4. Per-stop invoicing from the field. The invoice should exist before the truck leaves the curb — generated from the completed service, not re-typed at the office at 9 PM.

5. Quoted one-off work. Bed bug jobs, exclusion work, termite treatments, and initial cleanouts are estimated work with real margins. Line-item quotes with photos, approvable from the customer's phone, are how that work gets won.

6. Chemical-use documentation — know your state's rules. Most states require licensed applicators to keep records of pesticide applications (product, EPA registration number, rate, target pest, site). Dedicated pest platforms build structured chemical logs for this; general-purpose tools record service notes and photos but not regulator-formatted application logs. Whatever software you pick, confirm it satisfies — or you separately maintain — your state's record-keeping requirement. We'll be honest below about which category each tool falls in, including Krib.

Pest Control Invoicing: Close Out Every Stop Without Office Time

The pattern that fixes billing in this trade is simple to state: the service visit and the invoice should be the same motion. Here's what that requires from software:

Invoice from the completed stop. Tech marks the service complete; the invoice generates from it — same customer, same service, same price, notes attached. No evening data entry, no stack of paper tickets riding around in the truck.

Payment link or QR on the spot. For residential one-offs especially, the highest-percentage moment to collect is while you're standing there. A QR code on the invoice — customer scans, pays by card, done — beats "we'll mail you something" every time. (More collection tactics in our contractor invoicing guide.)

Plan billing for recurring accounts. Quarterly customers shouldn't get surprise paperwork — their invoice should follow each scheduled treatment automatically, or roll up on the cycle you've agreed.

An accounts-receivable view. Every unpaid invoice, sorted by age, in one list. At pest control volume this is the difference between following up on 12 specific invoices and having a vague sense that "some people owe us."

Books that reconcile. QuickBooks sync so the office (or your accountant) isn't re-keying hundreds of small invoices a month.

At 15 stops a day, shaving even three minutes of billing admin per stop returns most of an hour daily — that's the concrete case for software here, free or paid.

What Paid Pest Control Software Costs in 2026 (Verified)

The dedicated pest control market splits into one transparent mid-market tool and a set of quote-only enterprise platforms. Pricing verified 2026-07-18 on each vendor's official site.

GorillaDesk — the transparent one, and popular with small operations. Basic at $49/month (or $539/year), Pro at $99/month ($1,089/year), Growth at $149/month ($1,639/year). Pricing is per route/schedule rather than per user — admin users are unlimited, but each tech running a schedule needs a paid route, so a three-truck operation on Pro is ~$297/month. Month-to-month with no contracts, and a free trial (not a free tier). SMS costs extra ($5/month plus credit packs). Pro is where the customer portal, online booking, and review tools live. (Verified 2026-07-18 at gorilladesk.com/pricing.)

FieldRoutes — quote-only. No prices published anywhere on the pricing page; their FAQ discloses the model — "the monthly subscription is based on the number of active customers" — which means your software bill scales with your account list. Demo-first sales process. (Verified 2026-07-18 at fieldroutes.com/pricing.)

PestPac (WorkWave) — quote-only. Three tiers (Small Business, Professional, Enterprise), no published numbers; "speak with a consultant" is the pricing page's operative sentence. Third-party sources describe modular add-on pricing, but nothing verifiable from the official page. (Verified 2026-07-18 at pestpac.com/pricing.)

Briostack — quote-only. No pricing page exists on the official site; the only path is a demo request. (Verified 2026-07-18 at briostack.com.)

What this market structure means for a small operation: below roughly 500 accounts, you're choosing between $49–$149+/month per route on GorillaDesk or a sales process designed for companies with a fleet. The quote-only platforms are genuinely built for scale — routing optimization across dozens of trucks, call centers, M&A roll-ups — and their pricing reflects who they're for.

What "Free" Means in Pest Control Software

Unlike lawn care (where LawnPro and Yardbook offer real free tiers), the pest-specific software market has essentially no free tier at all. What you'll actually find behind "free pest control software" searches:

Free trials. GorillaDesk's trial is a real trial of a good product — but it's a paid product. Day one of the trial is day one of a $49–$149/month per-route decision.

Generic free tools. Spreadsheets, Google Calendar, invoice generators. Free, but they fail the recurring-plan and per-property-history tests immediately — recurring quarterly visits managed by spreadsheet is exactly how stops get missed.

Genuinely free general FSM platforms. Krib charges no subscription, no per-route fee, and no per-user fee; it makes money from an optional 0.1% platform fee on payments processed through it (plus standard Stripe fees), and from aggregated, anonymized property insights you can opt out of. It covers the recurring plans, scheduling, per-stop invoicing, payments, and service history — the honest trade-off is that it's not pest-specialized, which matters for one thing in particular: regulator-formatted chemical application logs, covered below.

The test: ask what the bill is per route, per user, and per customer — and whether the answer changes when truck #2 shows up.

Krib — Free Software for Pest Control Operations

Krib is a genuinely free field service platform that covers the core pest control workflow — recurring plans, dense daily schedules, per-stop invoicing, online payments, and permanent per-property service history — at $0/month with no per-route, per-user, or per-customer fees.

What's included free for a pest control business:

Recurring services for treatment plans. Set a customer's plan once — quarterly, bi-monthly, monthly — and visits regenerate on cadence, tied to the property, ready to schedule and invoice. Plans pause or cancel cleanly.

Scheduling built for stop density. See each tech's day at a glance, group stops by route day, and reshuffle when a bed bug call preempts the afternoon. Techs get a PIN-based mobile portal with their own stops, addresses, and property notes — no per-seat charges.

Per-stop invoicing with on-site payment. Completed service becomes the invoice in one step; send it with an online payment link or show a QR code at the door. The accounts-receivable dashboard keeps every unpaid invoice visible by age.

Permanent property records. Every treatment, note, and photo accumulates on the property — the tech's pre-visit briefing and your callback-dispute answer. Customers get a homeowner portal showing their own service history, which quietly differentiates you from the truck-and-clipboard competitor.

Quotes for the high-margin one-offs. Bed bug protocols, exclusion work, and initial cleanouts get line-item quotes with photos and good-better-best options, approvable from the customer's phone.

Booking widget with lead capture. Every "do you handle roaches?" request from your website or Google Business Profile auto-creates a lead in the CRM inbox for follow-up.

Full Spanish support across the whole workflow — scheduling, the tech portal, quotes, invoices, and customer messages — plus QuickBooks sync, timesheets, and customer chat.

How does Krib make money if the software is free? Krib uses Stripe to process payments. When you collect a digital payment from a customer, standard Stripe processing fees apply (2.9% + 30¢), plus a tiny 0.1% platform fee. You only pay when you get paid, and you can pass those processing fees onto the customer (subject to local laws). Additionally, Krib monetizes by creating aggregated, anonymized property history insights for industry partners (which you can opt out of).

If you don't use Krib to process payments, the software is entirely free to use forever.

The honest limitation, stated plainly: Krib does not produce regulator-formatted pesticide application logs. Service notes and photos document what happened, but if your state requires structured chemical-use records (product, EPA number, application rate, target pest), you'll need to keep that log separately — as many small operators already do — or choose a pest-specialized platform and pay its rates. Krib also doesn't do algorithmic route optimization; scheduling groups stops by day and tech, which covers most operations under a few hundred accounts.

• Recurring services for quarterly/bi-monthly/monthly treatment plans
• Dense daily scheduling with tech assignment and route-day grouping
• Tech PIN portal + timesheets — no per-user or per-route fees
• Per-stop invoicing with online payment links and QR codes
• Accounts-receivable dashboard for overdue follow-up
• Permanent per-property service history with photos + homeowner portal
• Line-item quotes for bed bug, exclusion, and cleanout work
• Full Spanish support, QuickBooks sync, booking widget with lead capture

• Best for: Solo operators and small pest control companies (1–5 techs) that want recurring plans, per-stop invoicing, and clean payment collection without per-route software bills — and can keep chemical-use logs to their state's format separately.
• Pricing: Free — $0/month, no per-route, per-user, or per-customer fees, no trial period. Standard payment processing fees (2.9% + 30¢ + 0.1% platform fee) apply only when you collect payments through the app.

How to Set Up a Free Pest Control Stack, Step by Step

From paper tickets to a working system in an afternoon:

Step 1: Create your free account and enter your service list. General pest treatment, quarterly service, flea/tick, rodent station check, bed bug prep inspection — each with realistic durations and prices.

Step 2: Load your recurring accounts. Each active plan customer with cadence and route day. This is the long step; it's also the one that ends missed treatments.

Step 3: Add your techs. PIN logins for the mobile portal, at no cost. Assign route days.

Step 4: Close out stops with invoices for one full week. Complete each service in the app, generate the invoice on-site, send with a payment link or QR. This is the habit that captures the unbilled-stop leak.

Step 5: Put the booking link on your website and Google Business Profile. Requests become leads automatically.

Step 6: Decide your chemical-log approach. If your state requires structured application records, keep your log (paper or spreadsheet) alongside Krib's service notes and photos — attach the photo of the log entry to the visit if you want everything findable per property.

Total cost: $0, plus whatever your state's record-keeping habit already costs you.
