How the switch works
2. Import your customers
Gaffer's one-click data import reads your file and maps the columns to the right fields, bringing every contact and site across in minutes.
3. Bring jobs across
Open and historic jobs land with their status, dates and notes intact, so your whole job history is searchable from day one.
4. Quotes & invoices too
Quotes arrive with their line items and invoices with their outstanding balances, so you can keep chasing payment without missing a beat.
5. Run both in parallel
Keep BigChange live for a short overlap while your team gets comfortable in Gaffer. Re-running the import updates existing records rather than creating duplicates, so it stays in sync.
6. Go live
Once everything checks out, do a final import, point your team at Gaffer and cancel BigChange. See the full feature list and pricing before you commit.
What comes across
Everything you need to keep working day one — pulled from your BigChange export into Gaffer.
- Customers & contacts, with addresses and sites
- Job history — open and completed, with status and notes
- Quotes & line items, ready to re-send or convert
- Invoices & outstanding balances, so payment chasing continues
- Compliance records start fresh in Gaffer's UK trade packs (CIS, Gas Safe, EICR, FENSA, RAMS)

What you actually get with Gaffer
Rather than tell you what BigChange does or does not do — their product, their roadmap — here is exactly what is in the box on our side, with the numbers. Every figure is what the platform ships today.
| Capability | In Gaffer | What that means on the job |
|---|---|---|
| Trade certificates & forms | 913 built in | Gas Safe records, EICRs, minor works, FENSA, RAMS — completed on site, signed, PDF issued before you leave. |
| UK trades with a ready-made pack | 58 trades | Your trade’s own forms, quote templates and workflows switched on from day one — not a form builder to configure. |
| Priced quote templates | 218 templates | Start from a real list of line items for the job in front of you rather than an empty quote. |
| Health & safety records | 39 features | Risk assessments, permits, statutory inspections, HAVS exposure, health surveillance — with review dates that surface before they lapse. |
| Accreditation guidance | 30 UK schemes | CHAS, Constructionline, NICEIC, ISO 9001 and more, each with its real requirements, evidence, cost and renewal period. |
| Public sector tendering | Live feed | Contract notices from the government’s Find a Tender service, filtered to your trades, with AI-assisted bid drafting. |
| Field app | 220+ screens | Offline-first throughout — lofts, plant rooms, rural sites. Captures on the device and syncs when signal returns. |
| UK finance | CIS & MTD VAT | Construction Industry Scheme deductions, MTD-ready VAT summaries, retention and variation orders handled the way UK trades need. |

Switching from BigChange: common questions
How long does it take to switch?
Most businesses are up and running in an afternoon. Exporting and importing takes minutes; the rest is checking everything looks right and getting your team comfortable, which is why we suggest a short overlap running both tools before you go live.
Will I lose any data?
No. Customers, contacts, job history, quotes with line items and invoices with balances all come across. Because re-running an import updates records rather than duplicating them, you can keep importing right up to go-live so nothing is missed.
Can I import a CSV export?
Yes. Gaffer's one-click data import accepts CSV exports and maps the columns for you. Where an API is available we can connect directly instead, but a CSV is always enough to get everything in.
Is there a cost to switch?
No. Importing your data is included and you start on a 14-day free trial with no card required. You only pay once you decide to stay, so you can move across and test everything at no risk.
