Comparison: Commusoft
Estimark and Commusoft, compared for UK firms
Commusoft is field service software built around service and maintenance businesses, with the heating and plumbing trades at its centre, and it is sold into the UK and beyond. Estimark carries reactive maintenance on priority SLAs as one module of a wider record: the same job that was quoted, costed and invoiced is the one the repair is raised against, and CIS, the VAT domestic reverse charge and Construction Act payment dates apply to it without anybody moving data between systems.
Where a service business meets a contracting one
Two halves of the same firm
Most maintenance firms also install. Running the reactive work in one product and the installation work in another means a second price book and a monthly reconciliation.
Subcontracting under CIS
A maintenance contractor working for a housing association or a main contractor is invoicing under CIS. The deduction is on labour only, on a 6th-to-5th tax month.
Damp and mould on a clock
Awaab’s Law puts statutory timescales on damp and mould in social housing. A repair record without those timers is evidence that has to be assembled by hand afterwards.
What the commitment is
Read both vendors’ own terms on contract length and minimum users before you compare a monthly figure, because the monthly figure is not the whole commitment.
Comparison: how it works
Who is Commusoft built for?
Service and maintenance businesses, with heating and plumbing firms at the centre of its positioning.
- Its story is the service call: booked, attended, certified and billed, with the customer relationship around it.
- That is a real market and Estimark sells into part of it through reactive maintenance and property compliance.
NoteEstimark describes its own product here. For the other product’s current price and what it covers, read that vendor’s own site.
Who is Estimark built for?
UK firms doing both: the installation and project work, and the reactive maintenance that follows it.
- Reactive maintenance on priority SLAs, with Awaab’s Law damp and mould timescales and a resident reporting portal.
- The same job record carries the quote, the cost, the invoice, the CIS deduction and the certificates.
- CP12, EIC, EICR, Minor Works and PAT certificates with typed test results.
- Schedule of rates and van stock for the firms delivering measured work.
NoteEstimark records the CIS300 and locks it to its tax period. It does not file the return to HMRC on your behalf.
What does Estimark do about UK statutory construction work?
It handles the four obligations a UK contractor is judged on: CIS deduction, the VAT domestic reverse charge, Construction Act payment timing, and the safety records that go with them.
- CIS deducted on labour only, excluding materials, VAT and plant hire, on 6th-to-5th tax months, with HMRC verification when connected and the CIS300 recorded with both statutory declarations.
- VAT domestic reverse charge under section 55A: the statutory wording on the invoice, nil VAT, controlled per client.
- Payment applications with Construction Act dates, the pay less deadline calculated, and retention tracked to release.
- RAMS with operative sign-off, inductions, permits and a live muster roll, plus EIC, EICR, Minor Works, PAT and CP12 certificates with typed test results.
NoteEstimark records the CIS300 and locks it to its tax period. It does not file the return to HMRC on your behalf.
When would Commusoft be the better answer?
When the whole firm is service and maintenance, there is no subcontracting under CIS, and no commercial work is applied for.
- A pure domestic service business has no deduction to make and no payment application to submit.
- A firm whose buying criterion is the depth of the service-call workflow should compare that workflow directly on both vendors’ sites.

Questions
Estimark vs Commusoft: frequently asked
Is Estimark a Commusoft alternative?
For a UK firm that installs as well as maintains, yes. Estimark runs reactive maintenance on priority SLAs alongside quoting, job costing, CIS and payment applications, on one record. For a business that is purely domestic service work, compare the service workflow on both vendors’ own sites.
Does Estimark cover Awaab’s Law?
It carries the Phase 1 damp and mould timescales as timers on the repair, with the resident reporting portal and the evidence attached to the job. Phase 2 extends the statutory timescales to further hazard categories from 30 November 2026, and Estimark’s timers cover Phase 1 today.
Does Estimark issue CP12 certificates?
Yes, with typed test results, alongside EIC, EICR, Minor Works and PAT. They are attached to the property and the job rather than filed separately.
Is there a minimum contract?
No. Estimark is monthly, published at /pricing, with a 14-day free trial. For any other vendor’s contract terms, read that vendor’s own site.
