What it is
A payment plan (instalment plan) models a big purchase or goal with a total cost, optional money already paid (e.g. a deposit), and one or more future payments on specific dates — holidays, school trips, festivals, wedding deposits, car insurance split payments, and similar.
The app keeps three separate ideas clear:
1. Payment schedule (vendor) — what you still owe the provider and when. Drives Timeline, forecasts, and mark-paid. Example: deposit + three £700 instalments to the travel company.
2. Group split (shared plan) — who should pay what share of the total cost. Example: holiday £3,821 split 50/50 → Donna expected £1,910.84, Mark expected £1,910.84. This is the agreed overall split — not the same as what has gone into the pot yet.
3. Pot funding — actual money recorded as put into the assigned pot. Example: Donna £1,630, Mark £1,150 into the Greece Holiday pot. These rows do not move the pot — update them when someone transfers money in.
Left to pay — (on Group split and Pot funding cards) = expected share minus recorded pot funding, plus each person’s share of money moved out for other uses. Record the total under Pot moves out when editing the plan (or leave blank to sum Timeline pot moves). Example: Donna expected £1,910.84, funded £1,630, and her 50% share of £80 moved out adds £40 → £320.84 left to pay.
Status (RAG) — on shared-plan cards: On track (green) when left to pay is zero; Behind (amber) when some is still owed but under 25% of expected share; Well behind (red) when more than 25% of their share is still unfunded. The card stripe uses the worst status in the group.
Pot balance vs recorded funding: — the current pot balance can differ from total recorded funding — vendor instalments marked paid, spending from this pot, or money moved to another pot. Only marked instalments count as paid to the vendor. For left to pay, record moves out under Pot moves out (or use the Timeline sum). Pot balance alone is not used to infer who owes what.
Each plan is tied to a pot (e.g. Holidays). The pot is where money sits; the plan tracks vendor dates, group shares, and who funded the pot.
Why it matters
You can see whether you are on track before each vendor payment is due — in Overview, Timeline, Plan your outgoings, and Pot coverage. With a shared plan you can also see who has funded the pot, who still has left to pay toward their share, and whether contributions are uneven — without mixing that up with what is owed to the provider.
Unlike a normal bill (rent every month), a plan is for a finite schedule tied to one goal. Unlike Money owed (money coming in to you), instalment plans are money going out from your pot.
