How MjengoX works

A project represents one construction site or build you're tracking costs for: a house, an extension, a renovation. Every document you upload, every payment you record, and every material estimate belongs to a project, so your costs never get mixed across sites.

Occasionally the AI model we normally use is briefly unavailable. When that happens, MjengoX automatically retries with a backup model rather than failing outright, so most of the time you won't notice. A document only fails outright when the text genuinely couldn't be read at all (a very blurry photo, a corrupted file, or a file that's too large); you'll see a clear reason why, rather than a generic error.

Not usually. Standard mobile money confirmation messages follow a predictable format, so MjengoX reads the amount, date, and reference number directly, without needing AI at all, which is also why these don't use up a document (see Document credits). Less standard messages, like some bank SMS formats, fall back to the same AI reading step used for receipts.

A document is marked Needs review when it processed successfully but something about it is worth double-checking: the photo was harder to read than usual, or a document had more line items than could be processed in one pass. The data is saved either way; the flag is just a nudge to glance at it against the original.

When an AI-read amount is unusually large, MjengoX holds it out of your project totals until you confirm it's correct, a safeguard against a misread digit throwing off your whole budget picture unnoticed. Open the record, check the amount against the original document, and save it, even with no changes, to include it in your totals.

MjengoX checks new payments against ones already recorded in the project: either an exact match on a mobile money/bank reference number (a very strong signal, since real reference numbers are unique), or the same amount recorded within a few days of each other. If you're sure it's not a duplicate, you can confirm and add it anyway.

You can still record mobile money/bank SMS payments and manual cash entries at any time; those never use a document. Uploading another receipt or quotation for AI reading needs a top-up or plan purchase first; see Buying & upgrading.

From your Profile page, choose a plan or a top-up pack and pay directly: mobile money or card, through our payment partner Paystack. Your balance updates automatically as soon as payment completes, usually within moments.

Purchases made in the mobile app go through Google Play (Android) or the App Store (iOS), using whatever payment method is already on your Play Store or Apple ID account; no separate checkout, and the same purchase protections you'd expect from either store apply.

Yes, your document balance and plan belong to your account, not to any one device or platform. Buy on the website, use it in the app, or the other way around.

A receipt tells you what was bought; it doesn't always mean it was paid in full, immediately, or in one go. Some purchases are on credit, some are settled across more than one payment. Keeping the two separate means your records stay accurate even when payment doesn't happen the moment you upload the receipt.

MjengoX suggests likely matches automatically based on amount and timing: tap Link if one looks right. If you paid entirely in cash for the full amount, there's a one-tap Add cash payment shortcut instead. You can also browse and link any recorded payment manually.

Unpaid: no payment linked yet. Partial: linked payments add up to less than the receipt total. Paid: linked payments cover it in full. If a small shortfall is simply how it was settled (a rounded-down cash payment, for instance), you can accept it and mark the receipt paid without needing an exact match.

The AI estimate is a rough cost range based on the document processed. A vendor quote is a real price you've entered from an actual supplier, and whenever one's available, it's used as the true cost for that item instead of the estimate.

Your correction is saved immediately, and the item is also marked as reviewed, so if you ever reprocess the same source document, your edit is protected and won't be silently overwritten by a fresh AI reading.

Starter allows one project, permanently; archiving it doesn't free up a new slot. Builder and Professional have no project limit.

It makes the project fully read-only: nothing can be added, edited, or deleted from it. Everything stays visible and exportable. It's the recommended way to "close the books" on a finished build without deleting its history.

Yes, continue with Google or Apple, or register with an email and password. It's the same account either way.

Yes, any time, from your Profile page. Adding a password doesn't change or remove your Google/Apple sign-in; it just gives you a second way in.

Yes, see our Privacy Policy for the full details on how your data is protected and used.

Processing needs a connection, since it happens on our servers rather than on your device. If you lose connection mid-upload, nothing is lost; just retry once you're back online.

Reach out to support with your project name and, if it's about a specific document, roughly when you uploaded it; that's usually enough for us to find exactly what happened.
