When Northgate Moving & Fulfilment first contacted **papermart**, they were not looking for the cheapest box on the market. They were looking for a way to explain why some parcels arrived looking tidy while others looked as if they had been packed by two different companies.
The company, based in Rotterdam, runs two businesses from one warehouse: household moves and small e-commerce fulfilment. That mix means every day the packing team handles furniture blankets, fragile tableware, apparel, books, and an endless stream of boxes. The old system allowed each department to order from its own shortlist of suppliers. It was flexible in theory and chaotic in practice.
The turning point was quiet: a decision to measure what a packed order actually cost and to test whether one supplier could hold the line. papermart tissue paper and papermart bubble mailers became the two products that made the test concrete.
The Real Cost of Saying Yes to Every Supplier
At the beginning, Northgate's purchasing file had eight active suppliers. There were cartons from a regional wholesaler, thin mailing bags from an online trader, and a roll of recycled kraft bought on promotion. Every invoice told a slightly different story. The average cost per order looked acceptable because no one was looking at the total. When the warehouse manager added up the damage returns and the staff time spent comparing deliveries, the real cost was close to 19% above the price of the materials alone.
The damage rate for small parcels was around 6.2%, and a large share of that damage came from mailers that split along the flap. Meanwhile, customer service had a recurring conversation. A customer would call and ask whether Northgate could match the offer behind the 'u haul moving boxes free' promotion they had seen online. That phrase never matched reality, but Northgate had no clear answer. The lack of one catalogue made every sale feel improvised.
They had tried to reduce supplier count before. It failed because the two departments wanted different types of boxes. Movers liked heavy double-wall cartons; fulfilment staff wanted lighter boxes that did not inflate shipping weight. One generic supplier could not serve both. This time, instead of choosing a single product, Northgate mapped each task to a specific grade and gave papermart a chance to fill those grades.
Benchmarking Cost per Packed Order
The first benchmark meeting with papermart was less about product names and more about definitions. Northgate had never tracked cost per packed order. They knew what each roll of tape cost, but not what a typical shipment consumed. We agreed on a simple template: material bill, packing time, and delivery outcome. After two weeks, the average material cost per order was 1.86 EUR and the average packing time was 4.8 minutes. Neither number looked scary.
The benchmark changed what they bought. The team had assumed cheap padded mailers were a win. Their failure rate was 4.3%, while a slightly more expensive mailer failed only 1.1% of the time. Northgate chose papermart bubble mailers as the default for non-fragile small items. Because breakage was not only about mailers, they also replaced a dusty low-grade tissue roll with papermart tissue paper in two weights: 40gsm for wrapping clothing and 60gsm for tableware. The heavier tissue cost more, but the earlier roll tore on the first fold.
For larger cartons, the team had to answer a question that support agents heard weekly. Emails arrived with the subject line 'where to buy boxes for moving cheap' at least twice a week. Northgate's solution was a narrow range of three box sizes and a short instruction sheet. They bought that range from papermart's box programme, and the sheet explained how to fold moving boxes correctly and how to tape the bottom seam. That was not a dramatic invention, but it gave customers something to take home instead of an open-ended web search.
Results After Two Quarters
The pilot ran from September to February, chosen because it covered both quiet weeks and the holiday peak. It also forced Northgate to consolidate its order calendar, since papermart's delivery schedule ran twice a week. The cleanest result was the material cost per packed order. It went from 1.86 EUR to 1.58 EUR, about a 15% drop. The drop did not come from choosing a cheaper supplier. It came from using fewer substitute products and from buying in quantities that matched actual demand.
Damage trends were uneven. Small parcel damage fell from 6.2% to 2.8%, but one courier route stayed at 4.1% because that depot was handling pallets roughly. No packaging change could fix that. Northgate decided to mention the limitation in its internal review. That honesty made the rest of the results easier to trust.
Packing time was a more consistent story. The team saved about nine minutes for every ten orders, mostly because they no longer needed to search for the right roll or the right box. The warehouse manager also introduced a short daily checklist built around the same how-to-folding instructions. The number of returned crushed boxes dropped from 34 in October to 11 in February. If the pilot had run only from January to June, the improvement would have looked smaller and less believable.
What the Spreadsheets Missed
The most useful outcome did not show up in any average. Northgate's order-picking staff stopped arguing about which tape or tissue roll to use. That sounds small, but it removed dozens of micro-decisions from each day. The purchasing manager read one papermart delivery note instead of chasing three suppliers for credit terms.
There was a trade-off. papermart tissue paper is not the lowest-price option in the industrial packaging market. It has a more consistent finish and fewer loose fibres, and that costs a little more per roll. Northgate accepted the higher unit cost because the previous cheap roll created torn corners and dust complaints. The extra cost was buried inside the damage-return improvement.
Mareike Jansen, Northgate's operations manager, summed it up in a way that stayed with the team: 'We thought we needed to find cheaper cardboard. In the end we needed to measure what happened after the box left the building.' The next stage is to apply the same benchmark to furniture blankets and tape supplies. That will be noisier. But the company now has a process, not just a supplier decision. For papermart, that is the best kind of outcome.
