For online sellers

Selling online is the easy part. Recording it shouldn't be the hard part.

Marketplace sales, stock purchases, postage, platform fees — online selling has its own shape of income and cost. Quarter Day is being built to record it in those terms, not force-fit it into generic categories.

Product concept

Your recordsSample quarter

Made to fit, not just to fit in.

Sales, stock and fees, separated

Marketplace sales, the stock you bought to sell, postage and platform fees — each recorded as what it actually is.

Works across platforms

Sell on more than one marketplace? Record it all in one place rather than juggling separate exports.

One flat price

£8/month or £80/year planned — not a charge per storefront or platform.
