5 Ways Bulgarian SMEs Can Improve Working Capital in 2026

Accelerate Your Accounts Receivable

Money owed to you by customers is not money in your business. Every day an invoice goes unpaid, you are effectively lending cash to your customer — interest-free. For many SMEs, this is where the biggest pool of trapped cash sits.

The fix starts with three things: clear payment terms on every invoice (30 days maximum if possible), a consistent and immediate follow-up process when invoices become overdue, and a regular review of your ageing receivables report — at least weekly. If you don't know which customers are late and by how many days, you cannot manage the problem.

A metric worth tracking is Days Sales Outstanding (DSO) — the average number of days it takes to collect payment after a sale. Reducing DSO by even 5 days can unlock significant liquidity. For a business with €500,000 in annual revenue, a 5-day DSO improvement frees up roughly €7,000 in cash — immediately, without any new revenue.

Optimise Your Payment Terms with Suppliers

Most SME owners focus on what customers owe them — but equally important is when you pay your suppliers. Extending payment terms from 30 to 45 or 60 days keeps cash in your business longer, improving your liquidity without any operational changes.

This requires a conversation with your suppliers — and it works best when you have a good relationship and a track record of reliable payment. Many suppliers will agree to extended terms if you offer something in return: a longer contract, a volume commitment, or simply the consistency of always paying on time.

The metric here is Days Payable Outstanding (DPO). Increasing DPO is one of the quickest wins in working capital management — and one of the most underused by SMEs. A word of caution: don't extend terms so far that you damage supplier relationships or lose access to early-payment discounts, which can sometimes be worth more than the cash benefit of waiting.

Reduce Inventory to the Right Level

Inventory is cash in physical form — sitting on a shelf. Too much stock means cash is trapped in goods that aren't yet generating revenue. Too little means stockouts, lost sales, and damaged customer relationships. Finding the right balance is where many SMEs lose money without realising it.

Start by identifying your slow-moving and excess stock. Run a simple analysis of which products haven't moved in 60, 90, or 120 days — and make a decision about each: discount and liquidate, return to supplier, or stop reordering. Then look at your reorder points and safety stock levels: are they based on real demand data, or on instinct and habit?

The metric to watch is Days Inventory Outstanding (DIO) — how many days of stock you hold on average. Reducing DIO directly improves your cash conversion cycle. In practice, most SMEs find that they can reduce inventory by 10–20% without any negative impact on operations, simply by becoming more data-driven about ordering.

Build a Rolling Cash Flow Forecast

Most cash flow crises are not sudden — they are predictable weeks or months in advance, if you are looking. The problem is that most SMEs only look at their bank balance, not at what is coming. A rolling cash flow forecast changes this entirely.

A basic 13-week rolling forecast shows you every expected cash inflow and outflow for the next three months. It does not need to be complex — a well-structured spreadsheet is enough to start. What matters is that it is updated weekly, includes input from sales (expected customer payments) and operations (planned supplier payments), and flags any periods where your balance is projected to fall below a safe minimum.

With a forecast in place, you can take action before a problem occurs: delay a non-urgent purchase, chase a specific customer early, or arrange a short-term facility with your bank. Without one, you react to problems instead of preventing them. This shift — from reactive to proactive — is one of the most valuable things any SME can do for its financial health.

Understand Your Cash Conversion Cycle

The Cash Conversion Cycle (CCC) is the single most useful metric for understanding your working capital position. It measures, in days, how long it takes to turn your investments in inventory and accounts receivable into actual cash — after accounting for the time you have to pay your own suppliers.

CCC = Days Inventory Outstanding (DIO) + Days Sales Outstanding (DSO) − Days Payable Outstanding (DPO)

A lower CCC means your business is converting resources into cash more quickly. A negative CCC — which some highly efficient businesses achieve — means you collect from customers before you have to pay suppliers, which is an extraordinarily strong cash position.

For most Bulgarian SMEs, simply knowing your current CCC is the first step. Once you know it, you can set a target, track it monthly, and make decisions that systematically reduce it. Each of the four strategies above — accelerating receivables, extending payables, reducing inventory, and forecasting accurately — directly improves one or more components of your CCC.
