Breaking Free from Fax and Double Entry: A Digitalization Pattern for Wholesalers

The 'fax and double entry' pattern describes a workflow where orders arrive by fax, get copied by hand onto a paper slip, and are then manually re-entered into a core system or spreadsheet ledger — the same order information handled by hand three separate times. It shows up most often in industries with many trading partners and a strong paper culture, such as food wholesalers, general merchandise wholesalers, and materials distributors.

Note that this article is not a case study of any specific company. It is a generalized explanation of a challenge pattern and resolution process commonly seen among small and medium-sized businesses. Any company or figures mentioned are typical composites, not references to any real, identifiable business.

Consider a food wholesaler with around 20 employees and roughly 1 billion yen in annual revenue, as a typical example. It deals with about 150 trading partners — restaurants and retailers — and order intake methods vary wildly: phone, fax, email, and direct contact with staff all coexist. Fax orders alone account for roughly 60% of the total, and during the morning rush, two order-processing staff routinely wrestle with stacks of fax paper. Each fax gets copied onto a handwritten order slip first, then manually keyed into the core system to trigger shipping instructions. This three-step 'fax → handwritten copy → system entry' process became the main driver of overtime as the daily cutoff approached.

Companies like this often face an immovable constraint sitting right behind the process: the delivery truck's departure time. Shipping instructions must be finalized before the cutoff or the truck ends up waiting, which leaves order-processing staff with almost no slack in their day. During peak seasons, temporary staff are sometimes brought in to help with order entry, but they struggle to decipher handwriting quirks and abbreviated product names on faxes, generating frequent confirmation checks with veteran staff — keeping training costs stubbornly high.

This type of challenge goes deeper than 'too much paper.' The triple-handling process layers several structural problems on top of one another.

- Transcription errors in quantities or product codes lead to stockouts or shipping mistakes
- Fax volume spikes during busy periods (month-end, seasonal demand), chronically driving overtime and staff fatigue
- The work becomes tied to specific staff who alone can handle it, making time off difficult
- Order formats differ by partner, making it hard to standardize entry rules
- Paper slips are hard to search, so tracing past order history takes time

- Months 1-2: Inventory current order channels and volumes per partner, visualizing the correlation between fax share and order volume
- Month 3: Hold briefing sessions on Web ordering SaaS for the top 20 highest-volume partners (roughly 70% of total orders)
- Months 4-5: Issue accounts and provide walkthroughs to top partners first, setting a transition period where fax and the new system run in parallel
- Months 6-8: Monitor migration progress monthly, and introduce fax-OCR as a supplementary tool for partners who struggle to switch
- Month 9 onward: Continuously reassess further investment (such as EDI) based on the remaining share of fax orders

Initiatives like this are commonly discussed in the range of roughly 300,000 to 3,000,000 yen in initial cost, with monthly fees from tens of thousands to over a hundred thousand yen. However, the amount varies significantly depending on the number of partners, order volume, and whether integration with an existing core system is needed, so treat these figures as rough guidance only. When making an actual investment decision, it helps to reference typical development cost ranges and how to read a vendor quote, and to always obtain quotes from multiple vendors for comparison. Depending on conditions, IT subsidy programs can also reduce the initial burden.

When comparing quotes, look beyond the monthly fee to the cost of adding each new partner, any extra charge for data integration with the core system (API or CSV-based), and the scope of support included — checking these upfront helps avoid unexpected costs later. EDI and custom development in particular can swing widely in price depending on requirements, so it's worth putting the assumptions behind an initial estimate in writing before proceeding.

- Aiming to switch every partner at once is a frequent cause of stalled projects. Treating partners with very different order volumes and digital readiness the same way means the loudest resistance eats up all the project's time
- Starting a fax/Web parallel-run period without setting an end date means fax orders never actually go away
- If partner-side contacts are older or unfamiliar with digital tools, a walkthrough alone isn't enough — phone-based follow-up support is often needed for adoption to stick
- Internal staff, worried that their workload will suddenly shrink, sometimes keep using the old process unofficially

The fax-and-double-entry problem is structural and rarely resolves through staff effort or workarounds alone. Rather than aiming for an all-at-once company-wide switch, migrating high-volume partners first and deliberately designing a transition period where paper and digital coexist tends to be the faster path to lasting adoption. Comparing the trade-offs of each option against the makeup of one's own trading partners is the key step.
