When should I scan documents in-house rather than outsource?

In-house scanning makes sense for: day-forward scanning of a few pages daily, highly sensitive documents that cannot leave your premises, continuous small volumes (50-200 pages per day), or when you already own production scanning equipment. For one-off projects or large volumes, outsourcing is almost always more cost-effective.

Is It Cheaper to Scan Documents In-House or Outsource?

Q: Is in-house document scanning cheaper than outsourcing?

Usually not. When you factor in equipment (£5,000-30,000), software (£1,000-10,000+), staff time (often the biggest cost), maintenance, quality control, and the opportunity cost of diverting employees from their core work, in-house scanning typically costs more than outsourcing for projects over a few thousand pages.

It seems logical that buying a scanner and doing it yourself would be cheaper than paying someone else. But when you add up the real costs — equipment, software, staff time, quality control and the opportunity cost of diverting people from their actual jobs — in-house scanning is almost always more expensive than outsourcing for any significant volume.

The True Cost of In-House Scanning

Equipment

A desktop scanner (the kind you might already have in the office) can handle a few pages at a time. For serious document scanning, you need a production scanner — a machine designed to process thousands of pages per day with automatic document feeders, duplex (double-sided) scanning, and robust paper handling.

Production scanners cost between £3,000 and £30,000 depending on speed and capability. A mid-range production scanner capable of 60 pages per minute costs around £5,000-£8,000. It will also need regular maintenance — roller replacements, cleaning, calibration — costing £200-£500 per year.

Software

The scanner hardware creates images. You also need software for OCR, file naming, quality control and document management. Professional capture software (like Kofax, ABBYY FineReader Server, or OpenText Capture) costs £1,000-£10,000+ depending on features and licensing model. Free or low-cost alternatives exist but typically lack the automation and quality features needed for large-scale projects.

Staff Time

This is where in-house scanning costs really add up. Someone needs to:

Prepare documents (remove staples, flatten, sort)
Feed the scanner and monitor for jams
Check image quality and rescan problem pages
Name and organise files
Manage the output and storage

A competent operator scanning well-prepared A4 documents on a production scanner can process about 3,000-5,000 images per day. At a staff cost of £15 per hour (including employment costs), that is about £120 per day — or roughly 3-4p per page for the scanning itself. But preparation, quality checking and filing can easily double the time required, pushing the effective rate to 6-8p per page.

And this person is not doing their actual job while they are scanning. The opportunity cost of diverting a £30,000+ salary employee to operate a scanner for weeks or months is significant.

The Cost of Outsourcing

A professional scanning bureau charges 5-15p per page for standard A4 documents with preparation, OCR and quality checking included. They achieve lower per-page costs because:

Their scanners are faster and more efficient (150-300 pages per minute for high-end production scanners vs 30-60 for mid-range models)
Their operators are trained and experienced — they scan all day, every day
Their preparation workflows are optimised for speed
Quality control is systematic and built into the process
They spread equipment and overhead costs across many clients

Cost Comparison Example

A business needs to scan 100,000 A4 pages (mix of stapled and loose documents, roughly half double-sided).

In-House

Production scanner: £6,000 (amortised over the project if this is a one-off, or over 3-5 years if ongoing)
OCR software: £2,000
Staff time — preparation: 50 days at £120/day = £6,000
Staff time — scanning: 30 days at £120/day = £3,600
Staff time — QA and filing: 15 days at £120/day = £1,800
Maintenance/consumables: £200
Total: approximately £19,600 (about 20p per page)

Outsourced

Scanning with preparation, OCR and QA at 10p per page: £10,000
Collection and delivery: £150
Total: approximately £10,150 (about 10p per page)

The outsourced option costs roughly half as much, delivers higher quality (professional equipment and trained operators), and does not disrupt your team for three months.

When In-House Scanning Makes Sense

In-house scanning is practical in specific scenarios:

Day-forward scanning: Scanning new documents as they arrive (a few pages per day) where the volume does not justify outsourcing
Highly sensitive documents: Material so sensitive that it cannot leave your premises (though most professional bureaus have equivalent or better security)
Continuous small volumes: An ongoing need to scan 50-200 pages per day as part of normal workflow
You already own the equipment: If you have a production scanner from a previous project, the marginal cost of using it is lower
