The group said its operating profit for the year had increased 30% to over £5mln, while revenues had risen to £32mln from £21.6mln last year.
The increase was bolstered by an enlargement of the company following its acquisition of supply chain management firm Anisa, which it purchased in November 2017 for £12mln.
Sanderson added that its pre-contracted recurring revenues now totalled over £17mln, representing 55% of total revenue.
Looking ahead, the firm said it had a healthy order book following a “strong intake” in the second half of the year, with good sales prospects.
