Add-backs: what you can and can't add back when you sell your store

Short answer. Add-backs are costs in your accounts that a new owner won't have, like your salary, personal expenses or a one-off rebrand. Each one raises the profit a buyer values, but only if you can prove it with an invoice, a bank line and a reason. Costs the business needs to keep its revenue are not add-backs.

Key takeaways

• An add-back is a real cost in your books that won't exist under a new owner.
• The safe ones: one owner's pay, personal expenses, interest, depreciation, truly one-off items.
• The risky ones: ad spend, staff you "could cut", one-offs that happen every year.
• Normalising works both ways: unpaid work and below-market costs get subtracted.
• Every add-back needs a paper trail. One that fails in due diligence damages trust in the rest.

What is an add-back, exactly?

When a buyer values your store, they're not interested in the profit you paid tax on. They want the profit the business will make for them. The difference between the two is mostly add-backs.

An add-back is a cost that appears in your accounts but won't appear in the buyer's. Adding it back raises the profit figure, and because that figure is multiplied to reach a value, a euro of verified add-back is worth a lot more than a euro.

That's also why buyers read add-backs carefully. They know the incentive. Your job is to make each one easy to accept.

Which add-backs do buyers usually accept?

Your own pay

If the valuation is built on SDE, one owner-operator's full pay is added back: salary, director's fees, pension contributions and benefits paid by the company. If it's built on EBITDA, your pay is added back but a market salary for your role is deducted.

Personal expenses paid by the business

Your phone, your car, a family trip booked on the company card. These are fine to add back as long as you can show each one is personal. Expect the buyer to ask why they were there in the first place. It's better to stop running them through the business a year before you sell, so the P&L tells the story without footnotes.

Interest, depreciation and amortisation

Interest on a loan you'll repay at closing, and accounting entries that don't move cash, are standard add-backs for both SDE and EBITDA.

Genuine one-offs

Costs that happened once, for a reason that's over:

• a rebrand or a new website build;
• legal fees for a dispute that's closed;
• a 3PL migration;
• a stock write-off after a supplier's faulty batch, if it really was a single event.

The test is simple. Would a reasonable buyer expect this cost again in the next 12 months? If yes, it isn't a one-off.

Non-operating items

Income or costs that have nothing to do with selling your products: a gain on selling an old company car, a grant, the cost of a side project run through the same company. Take them out, both ways.

Which add-backs get pushed back?

Ad spend

"If we cut Meta by 20% we lose almost nothing" is a claim, not an add-back. Advertising that produces revenue is an operating cost. If you want to show that some spend was wasteful, the clean way is to actually cut it months before the sale and let the results show in the numbers.

People you could do without

The freelancer who handles customer service, the part-time designer, the agency. If the business needs that work done to keep its revenue, it's a cost. Only people whose work really won't be needed qualify, and you'll need to explain who does the work instead.

One-offs that repeat

A "one-off" product launch every spring, a "one-time" inventory write-off every year. Buyers look at two or three years side by side. If the item shows up each year, it's part of how the business runs.

Founder perks dressed as costs

A conference in an exotic location might have had a business reason. A buyer will still ask whether it produced anything. If you can't say what, add it back as personal and move on.

What gets subtracted?

Buyers normalise in both directions. Expect them to deduct:

• Unpaid work. Your partner doing customer service for free, a family member packing orders. Someone will need to be paid for that.
• Below-market costs. A stockroom rented from a relative at a friendly price, a supplier giving you terms they won't give a stranger.
• Missing costs. Software paid from a personal card, a freelancer paid from a personal account. Those costs exist, they're just not in the P&L.
• Your EBITDA replacement salary, if the buyer values on EBITDA.

Showing these yourself is a strong signal. It tells the buyer the rest of your numbers were built the same honest way.

How do I document add-backs so they hold up?

Build an add-backs schedule, one line per item:

Keep the invoices in one folder, named the same way. When the buyer's accountant checks them during due diligence, they should be able to tick each line in minutes.

Two more rules make a schedule credible:

1. Totals reconcile. Profit in the accounts plus add-backs minus subtractions equals the SDE or EBITDA you're presenting. No rounding gaps.
2. The same treatment across years. If an item is added back in one year, similar items in other years are too.

What does a schedule look like in practice? (illustrative)

The figures below are illustrative, to show how a buyer reads a schedule. They're not benchmarks.

A founder presents a store with €52,000 of pre-tax profit and five add-backs:

The founder's version of SDE is €103,500. The buyer's version, after rejecting the Meta line and treating the trade fair as recurring, is €91,300. That gap gets multiplied. Worse, the rejected line makes the buyer re-check every other number in the P&L, slowing the deal down.

The same store, presented with only the three solid add-backs and a note explaining the trade fair, starts the negotiation at €91,300 with full credibility. That's usually the better position.

Can add-backs be too large?

There's no formula, but proportion matters. When add-backs are a small adjustment on top of a business that's clearly profitable, buyers read them as housekeeping. When they turn a modest profit into a big one, every line gets questioned, and the doubts spread to the parts of your P&L that were fine.

If your add-backs are large, the best fix is time: separate personal and business spending now, so that the next 12 months of accounts need fewer explanations. Our guide to cleaning up your P&L before selling shows how.

What to do next

Add-backs are where a valuation is most often inflated, and where a sale most often loses trust later. A defensible list is worth more than a long one.

If you want a second pair of eyes on yours, request a free valuation. We look at 12 to 24 months of numbers, flag the add-backs a buyer is likely to accept or challenge, and send you a realistic range within 24 hours. Zero upfront costs, no commitment to sell.
