The problem
Your business shouldn't live in six different places.
When customer details are in Excel, photos are in WhatsApp and jobs are being chased by email, admin grows faster than the business.
◌
Lost context
Job notes, photographs and customer conversations scattered across different tools and devices.
⌛
Repetitive admin
People repeatedly typing, copying and chasing information that software should be handling for them.

FAQ
Questions small businesses usually ask.
Is Trefnio an app or a website?
Trefnio is a web-based business application. It runs in a modern browser, so the same system can be used on phones, tablets and computers without maintaining separate native apps.
Can you remove features we don't need?
Yes. The point of the platform is to configure the system around the business. Modules can be included, omitted or adapted to fit the agreed workflow.
Does the financial section replace Xero, QuickBooks or an accountant?
No. Trefnio can help track operational figures such as invoices, expenses, outstanding payments and job profitability. Formal accounting can remain with your existing accounting software and accountant.
Can Trefnio replace an existing spreadsheet?
Often, yes. A useful first project is taking a spreadsheet-driven process and turning it into a structured system with proper records, filtering, permissions and reporting.
Is this only for trades?
No. Trades and property services are a natural fit, but the platform can be adapted for other small businesses with repeatable workflows, customer records, jobs, inspections, documents or reporting.
