- Vehicles and equipment tracked for capital cost allowance
What we take off a Hamilton plumbing contractor’s plate
Service calls and project work, mixed together
Emergency calls and multi-day projects hit the books differently. We separate service revenue from project work so you can see what each actually earns.
HST on every parts run
The HST you pay on parts and fixtures is an input tax credit. We capture it on every purchase so nothing you're owed slips through.
Apprentice and journeyman payroll
Payroll runs on time with source deductions remitted to CRA, T4s ready at year-end, and records kept WSIB-ready.
Why Hamilton plumbers choose taxifi
Hamilton's economy has manufacturing bones and a renovation-era present: older housing stock being rebuilt street by street, waterfront and downtown redevelopment, and GTA spillover bringing new customers — and new competition — up the escarpment. It is a growth market that rewards businesses ready to scale cleanly.
For Hamilton's plumbers, the day-to-day reality is parts, emergency call-outs, and crew payroll moving faster than the paperwork behind them. taxifi's AI keeps the books current every day and a Canadian accountant reviews and signs the filings, so you can see which kinds of work actually pay before you book more of it.
Common questions
Do I charge HST on residential plumbing jobs in Ontario?
Yes — plumbing services in Ontario are taxable at 13% HST whether the customer is a homeowner or a business, once your business is past the $30,000 small-supplier threshold and registered. The flip side is that the HST you pay on parts, fittings, fuel, and tools comes back as input tax credits — taxifi captures both sides on every transaction for Hamilton plumbers.
Should I track parts separately from labour in my books?
It is worth it — parts carry costs and often markup, labour carries payroll, and mixing them hides which jobs made money. Books that split materials from labour job by job show your real margin per call, which is the number that should set your pricing. That level of detail is only realistic when the bookkeeping happens daily instead of in a year-end batch.
We're growing with Hamilton. Can taxifi scale as we do?
That is the design. The flat monthly price is quoted for the size you are now and revisited as you grow — adding payroll when you hire, HST filings as volumes rise, and advisory when the decisions get bigger. Growing Hamilton businesses shouldn't outgrow their bookkeeping every eighteen months.
I already have a bookkeeper or accountant in Hamilton. How hard is switching?
The switch is free: we deal with your current provider directly, collect your file and history, and take over the monthly work. Any catch-up is scoped and priced before you commit. Your part is about an hour, and mid-year is fine.
