Pest control is a scheduling business wearing an inventory business's clothes. A single commercial contract might mean twelve visits a year at four sites, each with its own device map, each visit consuming a measured quantity of a registered product that has to be traceable to a batch, a technician licence and a signed certificate. Business Central's Service Management module gets you part of the way: service items, service orders, service contracts and resource allocation are all there. Where it runs out of road is everything that makes pest control regulated rather than merely field-based. There is no recurring treatment plan that spawns the next visit automatically, no application-rate or dilution validation against a chemical register, no concept of a treatment certificate distinct from a service order report, and no renewal workflow that applies an annual uplift across a book of contracts. Firms fill those gaps with spreadsheets, a separate field app that does not talk to the ledger, and a person whose whole job is chasing renewals.

We build a Business Central extension that closes those gaps inside the system you already run your finances in. A Treatment Plan table drives recurrence — frequency, seasonality, per-site device counts — and a codeunit scheduled through a job queue entry generates the next service orders ahead of the window, assigning technicians by skill, licence expiry and route grouping so a day's work is geographically coherent rather than alphabetical. A Chemical Register table extends your item master with registration or EPA numbers, approved application rates, dilution ratios, re-entry intervals and restricted-use flags; the visit posting codeunit validates the recorded quantity against the approved rate before it will post, then writes the consumption through the standard item journal so stock and cost stay correct and lot tracking gives you batch traceability without a parallel system. Service reports and treatment certificates are Word or RDLC layouts bound to the visit record, produced with the products applied, the areas treated, the technician's licence details and a captured signature.

Technically it is a clean AL extension — table extensions on Customer, Item, Service Contract Header and Service Header, page extensions rather than modified base pages, and event subscribers on the service posting and contract routines so nothing in the base application is touched. That is what keeps you upgradeable across Business Central release waves. We ship dedicated permission sets so dispatchers, technicians and back-office staff see only what they need, and API pages exposing treatment plans, visits and chemical usage over REST API v2.0 and OData v4 — which is what makes a Power Apps or Power Automate field-capture flow, a Dataverse sync, or a Power BI compliance dashboard a configuration exercise rather than another project. Contract renewals get their own pipeline: a renewal queue with configurable price uplift rules, job queue reminders at your chosen lead time, and bulk regeneration of contracts so a hundred renewals is an afternoon, not a fortnight.

This is a build-to-order product, not an AppSource download. Nothing installs today. We start with a scoping call where we walk through how your branches actually dispatch, what your regulator requires on a certificate, how your renewals are priced and which Business Central version and environment type you run. From that we write a fixed scope and a fixed quotation. Once you confirm it, typical delivery is one working week: we develop against a sandbox copy of your database, hand you a build for UAT on that sandbox, fix what testing finds, then deploy to production with a documented rollback plan. You receive the AL source code and the git repository, so you are never locked to us — and we stay available through an agreed post-go-live support window while your team settles into it.
