Pomio CRM keeps amount and notes on the same deal. Giving every open deal an amount is the baseline for forecasting; the next question is what happens when that number moves. A silent change turns the pipeline into a spreadsheet nobody can explain. A short note keeps the story with the figure.
Why silent amount changes hurt the forecast
The weighted forecast multiplies amount by probability. If the amount drops from €40,000 to €28,000 with no explanation, the review cannot tell whether the customer cut scope, the seller offered a discount, or someone fixed a typing error. The same problem appears when the amount jumps up: was it an upsell, a corrected quote, or optimism? Without a note, managers re-ask the same questions every week, and the weekly pipeline review wastes time reconstructing history instead of deciding next steps.
What counts as a material change
Agree a simple rule. Material means the change would change how you talk about the deal in the review — typically more than a small percentage or a fixed euro threshold your team picks. Examples that always need a note: a discount granted, products removed or added, a multi-year term shortened, or a switch from list price to a package. Examples that can be exempt if you say so in writing: rounding to the nearest euro, correcting a VAT inclusion after you already enter amounts excluding VAT, or fixing an obvious typo of a few euros.
What the note should say
Keep it short and factual. One or two sentences are enough: what changed, by how much, and why. “Customer dropped module B; amount −€8,000” beats a vague “updated quote.” Tie the note to the same discipline as a note on a stage change: the point is not bureaucracy, it is so the next person reading the deal does not have to guess. If the change also affects probability or forecast category, say that in the same note or update those fields in the same edit.
Amount, probability and forecast category stay linked
Amount alone does not make a forecast honest. Probability should still follow the stage by default, and forecast category still decides what counts as pipeline, best case or commit. A discounted deal that stays in Proposal at the stage default can remain “pipeline” until there is a dated next step. Keep deals without a next step out of commit, and keep unqualified deals out of the forecast — a clean amount with a note does not rescue a deal that should not be there.
How Pomio CRM helps
In Pomio CRM each deal shows its amount, probability, forecast category and notes together. When someone changes the amount, the note stays on the deal. In the weekly review you can sort or filter deals whose amount moved, read the reason, and decide whether the forecast still matches what the team expects to close.
A practical checklist
Require an amount on every open deal; require a short note on material amount changes; define a small rounding threshold that needs no note; enter amounts excluding VAT if that is your house rule; update probability and forecast category in the same edit when the story changes; review silent or unexplained amount moves in the weekly pipeline review; keep deals without a next step out of commit; keep unqualified deals out of the forecast.
Further reading
Should every euro change need a note?
No. Agree a threshold for rounding and tiny corrections. Material changes — discounts, scope cuts, upsells — always need a short note.
Who may change the amount?
Anyone who owns the deal may change it, but the note is mandatory for material moves. If discounts above a level need manager approval, record that approval in the same note.
What if the amount changes because of currency conversion?
Treat a material FX move like any other material change: note the rate or the reason. Tiny daily FX noise can fall under your rounding exemption.
Does a note replace updating probability?
No. The note explains the amount. Probability still follows the stage default unless you override it with its own short note.
