Questions people ask before they get in touch.

Replaces the spreadsheets a growing business depends on and only one person understands with one system, built on Microsoft Power Platform in your own Microsoft 365, or as a properly built Excel workbook where that is the right answer. Jobs, costing and invoicing; recruitment and onboarding; client billing and portals; pay runs, rotas, approvals and management reporting.

Businesses of roughly five to fifty people where a spreadsheet has started to limit delivery, visibility or control: the file several people share, the tracker nobody trusts, the invoicing that happens when someone remembers. Sector does not matter much; the pattern does.

Because the system exists to produce numbers the business runs on: what a job cost, what is unbilled, what the margin is. A developer builds what you describe. A management accountant knows which numbers have to reconcile at month-end and builds so they do.

Yes. The person on the call maps the process, builds the system and trains your team. That is why the price is lower than a larger consultancy and why I take on a few builds at a time rather than many.

Thirty minutes. You tell me what the spreadsheet does, who depends on it and what breaks when it fails. I tell you whether a system is worth your money. If the scope is clear, you get a fixed quote; if not, the next step is a one-week Review. No preparation needed, though having the file open helps.

A week with your actual files and the people who use them, for £450. You get a map of the process, what to keep and rebuild, a licensing assessment against your Microsoft 365, and a fixed-price proposal. It is paid because it is a week of work you can take elsewhere; the £450 is credited in full against a build that starts within 60 days.

Excel systems two to three weeks. Applications four to ten weeks, depending on how many processes, how many people and how much automation. The timescale is in the proposal before you commit.

It is quoted separately and built after the agreed scope, so the price and the deadline you signed up to do not move.

Both. On site across London and the south east where it helps, which it often does for the mapping and the training; remotely for everything else and for everyone further away.

Review £450, credited against the build. Excel systems from £900. Applications from £3,000, with most landing between £5,000 and £12,000. Support £250 a month, optional. All fixed price, excluding VAT. The full terms are on the Packages page.

Microsoft licences, which you pay to Microsoft and which the Review quantifies before you commit. Nothing else: no hosting, no hourly billing, no exit fee. You own the solution files and the documentation.

Agreed in the proposal before the build starts, typically a deposit on approval and the balance on handover. The Review is paid up front.

Up to three hours a month of fixes, small changes and new reports, with a reply within two working days. Time is logged and shown to you each month; unused hours do not carry over; a new module or change of scope is quoted separately. No minimum term.

A Microsoft 365 subscription for the business. Most companies on a Business Basic, Standard or Premium plan already have what a build starts from. If you are on Google Workspace, an Excel system or a conversation about what moving would involve is the honest starting point.

In your own Microsoft 365 tenant, in a Power Platform environment set up for your business, under security roles you control. I am given access for the build and removed afterwards unless you keep support. Nothing sits on my servers.

Yes. You get the solution files, the documentation and the training, and the system is built with standard Power Platform components that any Power Platform developer can pick up. There is no exit fee and no lock-in.

Small changes, such as adding a field or a view, can be made by a confident administrator after the handover training. Larger changes are quoted or done on support. The documentation says which is which.

No. Castlane builds on Power Apps, Power Automate, Power BI, Power Pages and Dataverse, plus Excel. If your business needs something else, I will say so on the call rather than bend the tool to fit.
