Comparison: simPRO

Estimark and simPRO, compared for UK contractors

simPRO is trade contracting and field service software aimed at established contractors running projects and maintenance side by side, sold internationally through a guided implementation. Estimark is a UK product for trades and SME contractors, published at a price you can read before you speak to anybody, with CIS, the VAT domestic reverse charge and Construction Act payment dates built into the documents rather than configured onto them.

What a UK buyer is choosing between

How you buy it

One product is bought through a sales process and an implementation. Estimark publishes every plan and module figure at /pricing and starts on a 14-day trial.

Where the statutory work lives

CIS, section 55A and the Construction Act are UK obligations. Software written for several markets treats them as a configuration, if it treats them at all.

How long it takes to be live

An implementation buys you a system shaped to your process and costs you the months before it runs. A self-serve product costs you the shaping and gets you running this week.

Who is on the tools

On an SME contract the person entering the data is the person on site. A product that assumes a back office assumes staff that are not there.

Comparison: how it works

Who is simPRO built for?

Established trade contractors and field service businesses running project and maintenance work together, sold across several countries.

Its positioning is the contractor with enough scale to justify an implementation and the process to shape around it.
That is a real market and it overlaps with the top of Estimark’s.

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 SME contractors who want to price the software, start it, and be invoicing correctly the same week.

Payment applications on Construction Act dates, pay less notices and retention tracked to release.
Job costing with actual, committed and forecast cost, and a cost value reconciliation pack.
CIS and the reverse charge applied to the document rather than remembered by a person.
Reactive maintenance on priority SLAs alongside the project work, on the same record.

NoteEstimark holds no security certification: no ISO 27001, no SOC 2, no Cyber Essentials. If your procurement requires one, Estimark cannot meet it today.

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 simPRO be the better answer?

When the firm is large enough to want a shaped implementation, or when a process already exists that the software has to match rather than replace.

A contractor with an established back office and a process it will not change is buying configuration, not defaults.
A firm operating outside the UK needs a product that carries more than one country’s tax rules.

Questions

Estimark vs simPRO: frequently asked

Is Estimark a simPRO alternative?

For a UK trade or SME contractor, yes. Estimark covers project and maintenance work on one record, handles CIS and the VAT domestic reverse charge, and runs payment applications on Construction Act dates. Estimark is UK-only, so a firm trading in several countries is a different question.

Does Estimark do payment applications and retention?

Yes. Applications with the due date, the final date for payment and the pay less deadline calculated from the Construction Act, with retention tracked to release. It is included from Pro.

How long does it take to get started?

There is a 14-day free trial and no implementation project. A card is taken at sign-up and nothing is charged until the trial ends.

Which is cheaper?

Estimark publishes every plan and module price at /pricing. Compare it against the other vendor’s own current pricing rather than a figure quoted on a third-party site.
