Summary

  • Bytes estimates that H1 FY27 Gross Invoiced Income rose about 19% and Gross Profit about 18%, while Operating Profit rose only about 6%; the company attributes the gap to strategic-project technology costs and bonuses returning to more normal levels.
  • Cash conversion improved from 34% to about 45%, but the company says cash generation is normally weighted to the second half; approximately £68 million of period-end net cash came after £41.3 million of dividends and buybacks.

The most conspicuous number in Bytes Technology Group’s 17 September trading update is 19%. It is also the easiest one to misuse. The company estimates that Gross Invoiced Income, or GII, increased by about 19% in the six months to 31 August 2026. That is not an estimate of IFRS revenue growth. It is a non-IFRS measure of gross income billed to customers, adjusted for deferred and accrued revenue, and it has a direct relationship with working-capital movements.

The distinction matters unusually much at Bytes. Under IFRS 15, contracts in which the group acts as agent are reported net: revenue is the gross profit retained on the contract, not the amount billed to the customer. Bytes’ FY26 results described hardware and internally supplied services as gross, principal activity, while software and externally supplied services were reported net as agent activity. A shift in product, vendor programme or billing route can therefore change GII and IFRS revenue on different scales without changing the underlying economics in the same proportion.

The update’s second number is consequently more informative. Bytes estimates Gross Profit grew about 18%, almost matching GII. That is a much stronger conversion than in FY26, when GII increased 11.5% to £2.341 billion but Gross Profit rose only 2.5% to £167.3 million. In that year, Gross Profit as a share of GII fell to 7.1% from 7.8%, partly because private-sector customers moved from Microsoft enterprise agreements, where Microsoft billed customers and paid Bytes a rebate, towards the Cloud Solution Provider programme, where Bytes billed the customer and paid Microsoft the cost of sale.

The accounting perimeter expanded faster than the retained economics.

No such mix table is included in the H1 FY27 trading update. The approximately 18% Gross Profit growth suggests that the current expansion is not merely a larger pile of low-margin invoices, but the evidence stops there. The statement gives no absolute H1 GII, IFRS revenue, Gross Profit or segment figures. The 13 October interim accounts need to show whether the improvement came from private or public customers, software or services, vendor incentives, pricing, new business, or a favourable comparison with the weak first half of FY26.

The third number creates the profit hinge. Operating Profit is estimated to have grown only about 6%. Management says the difference reflects previously communicated cost normalisation: higher technology costs connected with strategic projects and bonus levels returning to normal. That explanation is plausible and still unverified. The interim accounts must reveal whether those costs are temporary project expenditure, a durable increase in the operating base, capitalised development, or a mixture of all three. The relevant ratio is not GII growth alone but Operating Profit divided by Gross Profit, compared on a consistent basis.

Bytes has upgraded its full-year expectations: Gross Profit growth is now expected in the low-to-mid teens and Operating Profit growth in the low-to-mid single digits. This is guidance, not an achieved result. It also implies that the first half’s estimated 18% Gross Profit growth is expected to moderate, while Operating Profit growth remains structurally well below it. The spread is the price currently attached to investment, incentives and execution.

Cash adds a fourth ledger. H1 cash conversion was about 45%, up from 34% a year earlier. Bytes defines cash conversion as cash generated from operations less capital expenditure—its free cash flow—divided by Operating Profit. It is not a collection rate on revenue and it is not the period-end cash balance. The group says its cash generation is normally weighted to the second half. FY26 offers the seasonal reference: full-year free cash flow was £65.9 million on £62.7 million of Operating Profit, producing 105.1% cash conversion, near the group’s long-term target of about 100%.

The period-end net cash of approximately £68 million belongs in a fifth ledger. It was measured after £16.3 million of final dividend payments and £25.0 million of share repurchases, a total of £41.3 million returned to shareholders. Those distributions reduce cash, but they are capital allocation rather than operating cash consumption. Conversely, a healthy closing cash number does not prove that first-half working capital converted efficiently. Operating cash, investment expenditure, dividends, buybacks and the closing balance must be reconciled separately.

Management also says AI is becoming a more meaningful growth driver in Bytes’ core businesses. The update provides no AI revenue, GII, Gross Profit, order or customer split. For now, AI is a management description of demand, not a separately auditable growth engine. The October results may add evidence; until then it should not be used to explain the disclosed 19%, 18% or 6%.

The update is therefore stronger than a simple billing-growth headline and less complete than a profit-quality verdict. Gross Profit appears to be keeping pace with GII, but Operating Profit and first-half cash conversion lag. The investment case between now and 13 October is a chain of measurement gates: invoice scale, retained gross economics, operating-cost absorption, working-capital timing and capital allocation. Each number is encouraging on its own terms. None can substitute for the next.
