Both sectors are also signalling a much-improved position on the employment front.
The Scottish services sector has enjoyed a dramatic turnaround in its fortunes in the third quarter, according to the survey published today by British Chambers, while manufacturers north of the Border are signalling a sharp acceleration in the pace of increase of sales and orders in the UK market-place.
Liz Cameron, chief executive of Scottish Chambers of Commerce, described the findings of the survey relating to activity north of the Border in the third quarter as "very encouraging".
Commenting on the overall results, British Chambers declared its survey "provides further evidence that the UK economy is healing" with improvements in most key areas for both manufacturing and services, compared with the second quarter.
Subtracting the proportion of respondents reporting a fall from that experiencing a rise, while adjusting the findings to give larger companies a greater weighting, British Chambers' survey shows respective balances of 8% and 20% of Scottish services firms enjoyed rises in sales and orders in the UK market-place in the third quarter.
This was in stark contrast to the findings for the second quarter, during which respective weighted balances of 18% and 11% of Scottish services companies experienced falls in domestic sales and orders.
A weighted balance of 1% of Scottish services companies reported a rise in employment in the last three months. In the second quarter, a weighted balance of 26% of firms in this dominant sector of the economy north of the Border reduced employment.
Meanwhile, respective weighted balances of 28% and 30% of Scottish manufacturers reported rises in domestic sales and orders in the third quarter.
This signals much faster growth for Scottish manufacturers in the UK market-place than in the second quarter, when respective weighted balances of 3% and 13% of firms in the sector reported rises in domestic sales and orders.
Meanwhile, a weighted net 30% of Scottish manufacturers reported a rise in employment during the third quarter. A weighted balance of 15% of Scottish manufacturers had reported declining staff numbers in the second quarter.
A weighted net 15% of Scottish manufacturers reported a rise in export sales in the third quarter, an identical balance to that experiencing an increase in the second quarter. Meanwhile, a weighted net 21% of manufacturers north of the Border reported a rise in export orders in the last three months, down marginally from a corresponding balance of 24% in the second-quarter survey but nevertheless pointing to a continuing solid increase.
Ms Cameron said: "The results for this quarter are very encouraging and there is plenty to be optimistic about. All the key indicators show an improvement on Q2, with some improving by a significant margin. The strength of the domestic market is particularly encouraging. In Q2 many of the indicators were in negative territory but in Q3 most returned to positive."
However, she was surprised by falls in firms' confidence about prospects over the coming 12 months in the latest survey.
A weighted balance of 17% of Scottish manufacturers predicted profitability would worsen over the next 12 months. This contrasted with a weighted balance of 12% predicting improved profitability on a 12-month view in the second-quarter survey.
Meanwhile, a weighted balance of 15% of Scottish services companies predicted a deterioration in profitability over the coming 12 months. In the second-quarter survey, a net 2% of services firms north of the Border had predicted a worsening of profitability on a 12-month view.
Ms Cameron said: " The one surprising result was the fall in confidence about the next 12 months in both sectors. More must be done to help business growth. Action on reducing the burden of business rates would be very welcome."
