Greetings
I am currently a Power User on my main account (Business A - IT Consulting), which I just renewed for the year on 1st March 2026. My transaction volumes on this account are very low now (roughly 10–12 sales invoices and under a dozen purchase receipts per month). I operate as a Sole Trader under a trading name, so my personal name is the underlying legal entity.
I also have an existing, ongoing Sole Trader venture doing energy & telecoms sales as an independent agent under my own name. I have previously tracked this in Excel, but to prepare for Making Tax Digital (MTD), I now want to bring this data into QuickFile using an Affinity dashboard.
Please note that none of my businesses are VAT registered.
I would appreciate your confirmation on my structural plan and the billing details:
-
Business B (Energy & Telecoms Sales): I plan to open a brand-new, standalone standard QuickFile account for this business using a secondary email address.
-
Business C (Second Commission Stream): I am an authorised independent distributor for two separate Limited companies (neither of which are owned by me) and I receive commission payments from them. Business B gives me one commission payment per month (12 per year). Business C gives me one commission payment per month, though some months there is no commission at all (maximum 12 per year).
-
Expenses: There are zero expenses to log for the Business C income stream, but for Business B I do have a few operational expenses per month.
-
Using Project Tags: Since I am a Sole Trader getting paid under my own name for all my energy & telecoms activities, I understand that Business B and C are legally part of the same Sole Trader entity for HMRC. Instead of opening a 3rd QuickFile account, I intend to use Project Tags inside the Business B account to separate the two income streams.
-
Linking via Affinity: I want to open a QuickFile Affinity dashboard using my Business A email address and link both Business A (IT) and Business B (Energy & Telecoms) to it so I can switch between them under one login.
Could you please confirm the following billing questions for me?
-
Double Billing Check: Since Business A has an active, prepaid Power User subscription running until March 2027, will Affinity recognise this and charge me £0/day for managing Business A on the dashboard for the remainder of its subscription?
-
Business B Cost: Since Business B’s transaction volume will be exceptionally low (around 24 commission entries a year total across both streams, plus just a few expenses a month), it will sit comfortably in the Extra Small (XS) tier. Will its daily micro-fees simply deduct from the free £10 trial credit given upon starting Affinity?
-
Future Savings: When my Business A Power User subscription expires in March 2027, if I choose not to renew it and instead let both profiles run natively under Affinity’s pay-as-you-go daily rates, will the 1,000-posting Power User restriction disappear for both profiles? Given my combined low volume, will this be more cost-effective than paying for a flat annual subscription?
Thank you for your help and for confirming if this is the best path forward for my MTD transition!
