For a gas engineer, the invoice and the CP12 come out of the same job, so the best “invoicing” tool is usually the one that does the whole job. Here are the seven things that matter, and the tools worth comparing.
Full disclosure: we build Manifold. So rather than rank tools, here’s the checklist we’d hold any option to, including ours, with the head-to-head comparisons linked.
Score every tool you try against these, with your own jobs in mind.
The best tools turn a finished job into an invoice in seconds and let the customer pay by card on the spot, so you're not chasing money later. Look for card payments into your own account.
For a gas engineer, the certificate and the invoice come from the same job. Software that produces CP12s and gas records alongside the invoice beats stitching two tools together.
Lofts, basements and vans rarely have signal. You should be able to capture the job, raise the paperwork and take payment without a connection, and sync later.
For repeat gas work, software that tracks next-due dates and chases renewals turns one-off jobs into recurring revenue without you remembering who's due.
Invoicing is the end of the job. A good tool also holds the diary, the customer history and the appliances, so the whole day runs in one place.
Published per-engineer or per-user pricing and a genuine trial (ideally no card) let you judge a tool on your own jobs. Be wary of quote-only pricing you can't compare.
You should be able to bring your customers in from a CSV and get your data back out via an API or export. Avoid tools that make leaving hard.
Run each through the checklist above. Details reflect each product as publicly described in mid-2026 and change over time.
