Comparison: Payaca
Estimark and Payaca, compared for UK installers
Payaca is sales and job management software positioned at clean-tech and renewables installers, where the sale is a proposal with options and the delivery is an installation. Estimark is a general UK construction platform: it covers quoting, job costing, invoicing and the field work for any trade, and it carries the statutory obligations a UK installer meets on commercial work, including CIS deduction on labour only, the section 55A reverse charge and Construction Act payment dates.
Where an installer’s software has to reach
The sale and the site
A proposal wins the work. A RAMS, an induction and a certificate are what lets the team onto site and what proves the job was done properly afterwards.
Domestic and commercial together
An installer working for a housing association or a main contractor is subcontracting, which means a CIS deduction and often an application rather than an invoice.
Certificates with test results
An electrical installation produces an EIC or an EICR with typed values. A PDF attachment is a file; a typed certificate is a record you can search and re-issue.
What the entry point costs
Read both price pages against the size of your firm. Estimark publishes every plan and module figure at /pricing, starting at £39 a month +VAT.
Comparison: how it works
Who is Payaca built for?
Clean-tech and renewables installers, with the proposal and the installation at the centre of its positioning.
- Its story is the installer selling and delivering a system into a property.
- That is a vertical Estimark serves as one of many rather than as its whole market.
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 trades and contractors of any discipline, including installers who also do commercial and subcontract work.
- CIS deduction, the section 55A reverse charge and Construction Act payment applications on the commercial side.
- EIC, EICR, Minor Works, PAT and CP12 certificates with typed test results.
- Versioned RAMS with operative sign-off, inductions, permits and a live muster roll.
- Job costing with actual, committed and forecast cost across every job the firm runs.
NoteEstimark carries no MCS documentation pack, no DNO or ENA Connect submission and no integration with solar or heat pump design tools. An installer who needs those from one product should compare on that basis.
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 Payaca be the better answer?
When the firm is a renewables specialist and the requirement is the clean-tech sales and compliance chain from one product.
- MCS paperwork and DNO submissions are a real requirement and Estimark does not carry them.
- A firm whose whole pipeline is domestic retrofit has no CIS deduction to make and no application to submit.
